When did prenups become legal and enforceable in the UK?

Summary

A prenuptial agreement (prenup) is a legal contract couples sign before marriage, setting out how assets, debts, and finances will be handled if they separate. Once rarely used in the UK, prenups are becoming increasingly popular. In this guide, we explore when prenups became legally recognised, how they work, and what the future holds for prenuptial agreements in the UK. A prenuptial agreement (prenup) is a legal contract a couple signs before getting married, outlining how their assets, property, and finances will be divided if they separate or divorce. While often associated with high-net-worth individuals, prenups can benefit anyone - helping protect personal savings, business interests, future inheritances, or ensuring that assets from a previous marriage stay within a family. Prenuptial agreements aren’t automatically legally binding in the UK. Unlike in some other countries, UK courts don’t have to enforce them. Courts in England and Wales decide financial settlements based on factors like income and responsibilities, as set out in section 25 of the Matrimonial Causes Act 1973 and schedule 5 of the Civil Partnership Act 2004. Prenuptial agreements have existed in the UK for.

• Prenuptial agreements have existed in the UK for years, but they weren’t widely recognised by courts until 2010. The turning point came with the Radmacher v Granatino case, where the Supreme Court ruled that prenups should be upheld if both partners entered into them freely, with full financial disclosure, and the terms are fair. Since then, courts have given prenups significant weight, making them a valuable tool for financial planning in marriage.
• The Radmacher v Granatino (2010) case was a landmark moment in UK family law, setting a precedent for how prenuptial agreements are treated in divorce settlements.
• Katrin Radmacher, a wealthy German heiress, and Nicolas Granatino, a French investment banker, signed a prenuptial agreement before their marriage. The prenup stated that Granatino would not make any financial claims against Radmacher’s wealth if they divorced. Years later, their marriage ended, and Granatino challenged the agreement, arguing that he should receive a financial settlement despite what the prenup stated.
• The UK Supreme Court ruled in Radmacher’s favour, stating that prenups should be upheld unless they are unfair. This was a major shift in UK law, as courts had previously been reluctant to enforce these agreements. The ruling established key principles for prenups in the UK:
• They must be fair – Courts will not enforce prenups that leave one party in financial hardship. * Both parties must enter willingly – No pressure or coercion should be involved. * Full financial disclosure is required – Hiding assets can make a prenup invalid. * Independent legal advice is recommended – This ensures both parties understand what they are agreeing to.
